My reasoning for thinking there is still some air in the system is that the car is consistently in the 140 degree IAT2 (IAT after bricks). I feel like this is waaaayyy too high, however, I still have not received much feedback on what a stock ZL1 runs for IAT2 temps. One more note is following the car sitting when going into a store, etc. the temps get up in the 160-170 range and then pretty quickly drop...to the high 140s. Really the lowest I have seen is 64 degrees outside (low humidity) and still blower temps in the 120s...again a nearly 60 degree delta.
My ride is LT1 with the LT4 blower (2.3 upper at approx 610whp) and I would expect much lower temps with the WX system adding additional coolant.
What kind of temps can I expect out of this system? I mean this morning it is 84 degrees here in Houston and 54% humidity. I would not expect a nearly 60 degree delta between ambient and IAT2 temps. I have to get this solved or at least reassurance that somehow this temperature range is "normal" for the ZL1. I don't want to cause harm to either the blower or worse...the engine.

That doesn’t sound right to me. I watch my IAT2s from time to time on my P3 gauge. At a steady cruise with good airflow over the heat exchangers (like a freeway drive), my IAT2s are maybe 10-15 degrees above ambient.
When parking the car with a hot engine (like when going into a store for 20 minutes), it’s very normal for the temps to climb — but they should come back down to normal with some airflow. Still, I’ve never seen temps anywhere near what you’re reporting. I know it’s not nearly as hot on the California coast as it is in Houston, but we get the occasional heat wave. I’ve driven this car in 90+ degree weather, and have not experienced what you have.
I’ll look at some of my logs and pay closer attention to my live readings next time I drive the car, but I definitely think there’s air in your system or something else wrong.
